The Lumenier Mini 20 amp ESC with customized SimonK firmware including OneShot auto-detect is the perfect ESC to use on mini FPV quads such as the QAV250. This ESC is small in size (27x14.5x6mm) and big on power, supporting 20A on 4s. The ESC comes pre-loaded with the newest firmware, which is compatible with new features like "OneShot" (no soldering required, it will auto-detect if OneShot is enabled), Comp PWM (similar to KISS braking feature), compatible with all Lumenier motors up to 4 cell.

The Lumenier 20 amp AutoShot ESCs have been tested and are compatible with all Lumenier motors (RX1806, RX2206, RXC2206, RX2208), 2S-4S, both 5" and 6" props without sync loss issues or cogging.

The Simonk AutoShot firmware is pre-calibrated with endpoints 1060us - 1860us. This corresponds to the default endpoints in both Baseflight and Cleanflight(The ESC is configured for cleanflight/baseflight by default). Therefore, "Calibration" procedure is not necessary or recommended. "Calibrate" at your own risk. Removal of the red wire in the signal cable is ok if you don't need 5v power out, but both the ground (black) and signal wire (white) need to be connected to the flight controller. Do not connect only the signal wire alone.

More info: An ESC has either P-channel and N-channel FETs mixed or N-channel FETs only. The ESCs which use only N-channel FETs have the advantage of lower resistance, less losses and hence more efficiency. Learn more about N-channel and P-channel directly from Simon Kirby here.
